In Colombia, found the black boxes of the crashed plane

officials began their investigation into the deadly crash of a plane near Medellin, Colombia. The wreckage and "black boxes" will tell why the plane crashed.

The accident killed at least 71 people during a Charter flight in Medellin, including members of the football team of Brazil "Epicoene" who were going to play in the final of the Copa Libertadores. Three players, two crew members and one journalist survived, said Colombian authorities.

The lack of visible damage from a fire among the wreckage of the British Aerospace Avro RJ85 points to fuel starvation as one of the factors influencing the accident, which occurred on Monday. Fuel starvation occurs when fuel is cut off from the engines, forcing them to stop work. This can be caused by a number of factors, including leakage of fuel, failure of fuel pumps or sensors, or crew error.

The Director of Colombia's civil aviation, Alfredo Bocanegra, said that even though a preliminary investigation indicates an electrical problem that the plane ran out of fuel is not excluded, according to the Italian branch of the ANSA. However, investigators should find out why the plane had enough fuel, despite the fact that he was only 5 kilometers from the airport.

Colombian civil aviation refused to comment further technical details. The fuel shortage was "very, very rare from a commercial point of view of aviation, since there are so many checks and balances to make sure that you have enough fuel on Board," the investigator said Grant Brophy.

Investigators will reconstruct the last hours of the flight, using the information gathered from flight data and voice recorder, as well as maintenance and production records. The so-called "black boxes" was discovered on Tuesday morning and was in excellent condition, according to Colombian aviation professionals.
